可以实现任意文件的加密解密。高级加密标准（英语：Advanced Encryption Standard，缩写：AES），在密码学中又称Rijndael加密法，是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES，已经被多方分析且广为全世界所使用。经过五年的甄选流程，高级加密标准由美国国家标准与技术研究院（NIST）于2001年11月26日发布于FIPS PUB 197，并在2002年5月26日成为有效的标准。2006年，高级加密标准已然成为对称密钥加密中最流行的算法之一。(Encryption and decryption of any file can be achieved.Advanced Encryption Standard (English: Advanced Encryption Standard, abbreviation: AES), also known in cryptography Rijndael encryption method, is the U.S. federal government adopted a block encryption standard. This standard is used to replace the original DES, have been analyzed and widely used around the world. After five years of the selection process, senior study on encryption standard by the National Institute of standards and Technology (NIST) released in November 26, 2001 on FIPS PUB 197, and in May 26, 2002 became the effective standard of.2006, the advanced encryption standard has become one of the most popular symmetric key encryption algorithm.)
